Lua + RS-232, portable, just install?

[Enrico Colombini <erix@...>]

Reading the thread about LuaRocks, LuaDist and binaries...

I plan to write a portable script using serial communication, as part of 
a larger microcontroller educational project.
So that script would just be a corollary that should 'just work' without 
distracting my readers from the main task.

I'd rather use Lua than Python (also because data preprocessing is 
already done in Lua) but I am a bit lost in the libraries forest.
Is there a simple way for (mostly) clueless users to just install a 
single binary package on Windows/Linux/OSX and be able to execute a Lua 
script using RS-232 communication?

Or is there a better simple way to get that capability?
(where 'simple' = just run the installer and press OK)
